In this study, the authors investigated the degree to which a family investment model would help account for the association between family of origin socioeconomic characteristics and the later educational attainment of 451 young adults (age 26) from 2-parent families. Parents' educational level, occupational prestige, and family income in 1989 each had a statistically significant direct relationship with youths' educational attainment in 2002. Consistent with the theoretical model guiding the study, parents' educational level and family income also demonstrated statistically significant indirect effects on later educational attainment through their associations with growth trajectories for supportive parenting, sibling relations, and adolescent academic engagement. Supportive parenting and sibling relations were linked to later educational attainment through their association with adolescent academic engagement. Academic engagement during adolescence was associated with educational attainment in young adulthood. These basic processes operated similarly regardless of youths' gender, target youths' age relative to a near-age sibling, gender composition of the sibling dyad, or gender of parent.

This study examined the effect of changes in racial identity, cross-race friendships, same-race friendships, and classroom racial composition on changes in race-related social cognition from 3rd to 5th grade for 73 African American children. The goal of the study was to determine the extent to which preadolescent racial identity and social context predict expectations of racial discrimination in cross-race social interactions (social expectations). Expectations of racial discrimination were assessed using vignettes of cross-race social situations involving an African American child in a social interaction with European Americans. There were 3 major findings. First, expectations for discrimination declined slightly from 3rd to 5th grade. Second, although racial composition of children's classrooms, number of European American friends, gender, and family poverty status were largely unrelated to social expectations, having more African American friends was associated with expecting more discrimination in cross-racial interactions from 3rd to 5th grade. Third, increases in racial centrality were related to increases in discrimination expectations, and increases in public regard were associated with decreases in discrimination expectations. These data suggest that as early as 3rd grade, children are forming attitudes about their racial group that have implications for their cross-race social interactions.

The authors examined regulation of the discrete emotions anger and sadness in adolescents through older adults in the context of describing everyday problem situations. The results support previous work; in comparison to younger age groups, older adults reported that they experienced less anger and reported that they used more passive and fewer proactive emotion-regulation strategies in interpersonal situations. The experience of anger partially mediated age differences in the use of proactive emotion regulation. This suggests that at least part of the reason why older adults use fewer proactive emotion-regulation strategies is their decreased experience of anger. Results are discussed in the context of lifespan theories of emotional development. (PsycINFO Database Record (c) 2008 APA, all rights reserved)

The authors examined the effects of welfare programs that increased maternal employment and family income on the development of very young children using data from 5 random-assignment experiments. The children were 6 months to 3 years old when their mothers entered the programs; cognitive and behavioral outcomes were measured 2?5 years later. While there were no overall program impacts, positive or negative, on the development of children in this age group, there was a pair of domain- and age-specific effects: The programs decreased positive social behavior among 1-year-olds and increased school achievement among 2-year-olds. After exploring several explanations for these results, the authors suggest that the contextual changes engendered by the programs, including children's exposure to center-based child care, interacted differentially with specific developmental transitions.

Data from approximately 14,000 children in the Early Childhood Longitudinal Survey--Kindergarten Cohort were analyzed to examine the associations between children's immigrant status and their academic trajectories from kindergarten to 3rd grade, with particular attention to the effects of school environments. Growth curve modeling results indicated that most children of Latin American origin improved their reading and math scores faster than non-Hispanic White children, thus narrowing their initial score gap and sometimes even surpassing White children by 3rd grade. In contrast, although they maintained higher reading and math scores, children from East Asia and India showed decreasing scores over time, which tended to narrow their initial score advantage over non-Hispanic White children. School-level factors accounted partially for these differences. Particularly in terms of the academic trajectories, children of Latin American origin responded more to school-level factors than did children of Asian origin, who responded more to child and family background, with the exception of children from Vietnam, Thailand, Cambodia, and Laos, who responded more to school-level factors. Simulation results point to the importance of school resources for the academic trajectories of children of immigrants. (PsycINFO Database Record (c) 2008 APA, all rights reserved)

This study presents an extended children-of-twins model, which allowed the authors to test the direction of the association between parenting and child adjustment. Three mechanisms were examined: direct phenotypic influence of parenting on child behavior (controlling for both parental and child genotype), passive genotype-environment correlation, and evocative genotype-environment correlation. This model was tested with Monte Carlo simulations. The authors generated data sets consisting of 1,000 twin parent pairs together with their children and 1,000 twin children pairs together with their parents. These simulated data sets were then used to estimate the model, and the procedure was repeated 1,000 times. The simulation results showed that this model recovered the true values of parameters with high precision. The model was also applied to an observed data set to analyze, as a first example, the association between maternal emotional overinvolvement and child internalizing problems. The results showed that this association was best explained by evocative genotype-environment correlation. (PsycINFO Database Record (c) 2008 APA, all rights reserved)

Consistent with a holistic perspective emphasizing the integration of multiple individual characteristics within child systems, it was hypothesized that subgroups of anxious solitary (AS) children characterized by agreeableness, behavioral normality, attention-seeking-immaturity, and externalizing behaviors would demonstrate heterogeneity in peer relations and dyadic friendships. Sociometrics were collected for 688 3rd-grade children (mean age = 8.66 years, 51.5% female), and recess observations were obtained for a subset of 163 children. Results revealed that agreeable AS children demonstrated significantly superior relational adaptation relative to other AS children, whereas normative, attention-seeking-immature, and externalizing AS children demonstrated increasing relational adversity. Attention-seeking-immature AS children engaged in particularly high rates of directed solitary behavior and were most ignored by peers. Externalizing AS children were most often victimized by peers. Subgroup differences in sociometric peer adversity were qualified by sex. (PsycINFO Database Record (c) 2008 APA, all rights reserved)

This study tested whether pro-alcohol peer influences and prosocial involvement account for increases in drinking during the transition into emerging adulthood and whether these mechanisms differ depending on college attendance and/or moving away from home. The authors used structural equation modeling of prospective data from 825 young men and women. For 4 groups defined by college and residential status, more drinking in the spring of 12th grade predicted more pro-alcohol peer influences the following fall, and more pro-alcohol peer influences in the fall predicted increases in drinking the following spring. Going to college while living at home was a protective factor against increases in drinking and selection of pro-alcohol peer involvements. Prosocial involvement (measured by involvement in religious activities and volunteer work) was not significantly related to post-high school drinking except among college students living away from home. Prevention efforts should focus on (a) reducing opportunities for heavy drinking for college and noncollege emerging adults as they leave home and (b) increasing prosocial involvement among college students not living at home.

This longitudinal study was designed to (a) examine changes in children's deliberate memory across the 1st grade; (b) characterize the memory-relevant aspects of their classrooms; and (c) explore linkages between the children's performance and the language their teachers use in instruction. To explore contextual factors that may facilitate the development of skills for remembering, 107 first graders were assessed 3 times with a broad set of tasks, while extensive observations were made in the 14 classrooms from which these children were sampled. When the participating teachers were classified as high or low in terms of their "mnemonic orientation," in part on the basis of their use of metacognitive information and requests for deliberate remembering during instruction in language arts and mathematics, differences were observed in the use of mnemonic techniques by the children in their classes. By the end of the year, the children drawn from these 2 groups of classrooms differed in their spontaneous use of simple behavioral strategies for remembering and in their response to training in more complex verbally based mnemonic techniques.

This study examined whether the well-documented adult tendency to perceive gaze aversion as a lying cue is also evident in children. In Experiment 1, 6-year-olds, 9-year-olds, and adults were shown video vignettes of speakers who either maintained or avoided eye contact while answering an interviewer's questions. Participants evaluated whether the speaker was telling the truth or lying on each trial. The results revealed that at both ages, children were more likely to attribute lying to speakers in the gaze aversion condition; however, the effect was significantly greater among 9-year-olds. Significant gender differences were also uncovered, with girls demonstrating strongest sensitivity to the gaze cue. Experiment 2 replicated the gender effect in 6-year-olds but found that when the speakers' verbal responses were removed, boys' use of the gaze cue increased and the gender difference disappeared. These findings indicate that at 6 years old, children interpret interpersonal gaze behavior as a socially informative cue. Furthermore, the growing appreciation of the stereotypic gaze behavior associated with lying and the reputed female advantage in gaze sensitivity may reflect differential processing of multimodal communication.

Although the well-documented association between parental divorce and adolescent delinquency is generally assumed to be environmental (i.e., causal) in origin, genetic mediation is also possible. Namely, the behavior problems often found in children of divorce could derive from similar pathology in the parents, pathology that is both heritable and increases the risk that the parent will experience divorce. To test these alternative hypotheses, the authors made use of a novel design that incorporated timing of divorce in a sample of 610 adoptive and biological families. They reasoned that if genes common to parent and child mediate this association, nonadopted youth should manifest increased delinquency in the presence of parental divorce even if the divorce preceded their birth (i.e., was from a prior parental relationship). However, should the association be environmental in origin, the authors reasoned that adolescents should manifest increased delinquency only in response to divorce exposure, and this association should not vary by adoption status. Results firmly supported the latter, suggesting that it is the experience of parental divorce, and not common genes, that drives the association between divorce and adolescent delinquency.

This study examined how children's insecure internal representations of interparental and parent-child relationships served as explanatory mechanisms in multiple pathways linking interparental conflict and parent emotional unavailability with the emotional and classroom engagement difficulties the children had in their adjustment to school. With their parents, 229 kindergarten children (127 girls and 102 boys, mean age = 6.0 years, SD = .50, at Wave 1) participated in this multimethod, 3-year longitudinal investigation. Findings revealed that children's insecure representations of the interparental relationship were a significant intervening mechanism in associations between observational ratings of interparental conflict and child and teacher reports on children's emotional and classroom difficulties in school over a 2-year period. Moreover, increased parental emotional unavailability accompanying high levels of interparental conflict was associated with children's insecure representations of the parent-child relationship and children's difficulties in classroom engagement at school entry. The findings highlight the importance of understanding the intrinsic processes that contribute to difficulties with stage-salient tasks for children who are experiencing interparental discord.

The objective of the current study was to evaluate the patterns of longitudinal change in the language abilities of 28 children with autism during early and middle childhood. Results from fitting a series of multilevel models showed that children's rate of language growth was independently predicted by (a) children's responsiveness to others' bids for joint attention and (b) parents' responsiveness to their children's attention and activity during play. Both predictive relations could not be explained by initial variation in global developmental characteristics, such as IQ, mental age, or language abilities. These findings support a social?pragmatic view on language acquisition, which emphasizes the collaborative process through which children and their parents negotiate shared meaning.

The authors examined the effects of locomotor experience on infants' perceptual judgments in a potentially risky situation--descending steep and shallow slopes--while manipulating social incentives to determine where perceptual judgments are most malleable. Twelve-month-old experienced crawlers and novice walkers were tested on an adjustable sloping walkway as their mothers encouraged and discouraged descent. A psychophysical procedure was used to estimate infants' ability to crawl/walk down slopes, followed by test trials in which mothers encouraged and discouraged infants to crawl/walk down. Both locomotor experience and social incentives affected perceptual judgments. In the encourage condition, crawlers only attempted safe slopes within their abilities, but walkers repeatedly attempted impossibly risky slopes, replicating previous work. The discourage condition showed where judgments are most malleable. When mothers provided negative social incentives, crawlers occasionally avoided safe slopes, and walkers occasionally avoided the most extreme 50? increment, although they attempted to walk on more than half the trials. Findings indicate that both locomotor experience and social incentives play key roles in adaptive responding, but the benefits are specific to the posture that infants use for balance and locomotion.

In manual search tasks designed to assess infants' knowledge of the object concept, why does search for objects hidden by darkness precede search for objects hidden by visible occluders by several months? A graded representations account explains this décalage by proposing that the conflicting visual input from occluders directly competes with object representations, whereas darkness merely weakens representations. This study tests the prediction that representations of objects hidden by darkness are strong enough for infants to bind auditory cues to them and support search, whereas representations of objects hidden by occluders are not. Six-and-half-month-olds were presented with audible or silent objects that remained visible, became hidden by darkness, or became hidden by a visible occluder. Search required engaging in the same means-end action in all conditions. As predicted, auditory cues increased search when objects were hidden by darkness but not when they were hidden by a visible occluder. Results are discussed in the context of different facets of object concept development highlighted by graded representations perspectives and core knowledge perspectives and in relation to other work on multimodal object representations.

A longitudinal study and a training study were conducted to show that simply referring to others facilitated theory of mind (ToM) development in Chinese children. In Study 1, 3- to 4-year-old Chinese children (N = 52) were tested on ToM and autobiographical memory (AM). One year later, in the group of children who initially failed the false belief tasks, only those who increased their references to others in AM recall passed the tasks. In Study 2, Chinese preschoolers who were trained to talk about others through storytelling showed improvement in their ToM performance. These findings suggest alternative pathways for ToM development in non-Euro-American context. (PsycINFO Database Record (c) 2008 APA, all rights reserved)

The authors examined the longitudinal effects of the Family Check-Up (FCU) on parents' positive behavior support and children's school readiness competencies in early childhood. It was hypothesized that the FCU would promote language skills and inhibitory control in children at risk for behavior problems as an indirect outcome associated with targeted improvements in parents' positive behavior support. High-risk families in the Women, Infants, and Children Nutrition Program participated in a multisite preventive intervention study (N = 731) with 3 yearly assessments beginning at child age 2 years. Positive behavior support was measured using 4 indicators derived from at-home observations of parent-child interaction during semistructured tasks. Longitudinal structural equation models revealed that parents in families randomly assigned to the FCU showed improvements in positive behavior support from child age 2 to 3, which in turn promoted children's inhibitory control and language development from age 3 to 4, accounting for child gender, ethnicity, and parental education. Findings suggest that a brief, ecological preventive intervention supporting positive parenting practices can indirectly foster key facets of school readiness in children at risk.

Based on the idea that believers' perceived relationships with God develop from their attachment-related experiences with primary caregivers, the authors explored the quality of such experiences and their representations among individuals who differed in likelihood of experiencing a principal attachment to God. Using the Adult Attachment Interview (AAI), they compared attachment-related experiences and representations in a group of 30 Catholic priests and religious with a matched group of lay Catholics and with the worldwide normal distribution of AAI classifications. They found an overrepresentation of secure-autonomous states regarding attachment among those more likely to experience a principal attachment to God (i.e., the priests and religious) compared with the other groups and an underrepresentation of unresolved?disorganized states in the two groups of Catholics compared with the worldwide normal distribution. Key findings also included links between secure-autonomous states regarding attachment and estimated experiences with loving or nonrejecting parents on the one hand and loving God imagery on the other. These results extend the literature on religion from an attachment perspective and support the idea that generalized working models derived from attachment experiences with parents are reflected in believers' perceptions of God.

It has been hypothesized that sensation seeking and impulsivity, which are often conflated, in fact develop along different timetables and have different neural underpinnings, and that the difference in their timetables helps account for heightened risk taking during adolescence. In order to test these propositions, the authors examined age differences in sensation seeking and impulsivity in a socioeconomically and ethnically diverse sample of 935 individuals between the ages of 10 and 30, using self-report and behavioral measures of each construct. Consistent with the authors' predictions, age differences in sensation seeking, which are linked to pubertal maturation, follow a curvilinear pattern, with sensation seeking increasing between 10 and 15 and declining or remaining stable thereafter. In contrast, age differences in impulsivity, which are unrelated to puberty, follow a linear pattern, with impulsivity declining steadily from age 10 on. Heightened vulnerability to risk taking in middle adolescence may be due to the combination of relatively higher inclinations to seek excitement and relatively immature capacities for self-control that are typical of this period of development.

In most of our social life we communicate and relate to others. Successful interpersonal relating is crucial to physical and mental well-being and growth. This study, using the still-face paradigm, demonstrates that even human neonates (n = 90, 3-96 hr after birth) adjust their behavior according to the social responsiveness of their interaction partner. If the interaction partner becomes unresponsive, newborns will also change their behavior, decrease eye contact, and display signs of distress. Even after the interaction partner resumes responsiveness, the effects of the communication disturbance persist as a spillover. These results indicate that even newborn infants sensitively monitor the behavior of others and react as if they had innate expectations regarding rules of interpersonal interaction.
